Rise of the Triad: Dark War

Wait for one of the demos to start. While the demo is playing, press [F6] to quick save. Go to the main menu, and load that quicksave file. You will have "warped"
into the exact scenario in the demo, level and all.

When you encounter one of the infamous "push column mazes" or any columns you think could obscure a secret area,use the following this trick to check which columns move. Activate Shrooms Mode Power-Down by enabling the badtrip code, or find a Shrooms Mode pick-up. Now, look at the column you want to check. If you can move the column, or it moves in any way, the column will flash all sorts of strange colors. If the column does not move, it will remain the same as in normal mode. Be careful before trying this, as Shrooms Mode makes the game very difficult to play. Make sure the area is secure before using this trick.

When you enter the level, type in the code "flyboy" to put you in Mercury Mode. Then go straight until you come to the wall. After that go left. You fill find an extra guy in the air. Next, type the code "reen" to re-enter the level. Finally, do the same thing as before as long as you want.
